A wireless communication method and device are provided. The method comprises: a terminal device determining a reference uplink signal of a target uplink signal; the terminal device determining the transmission power of the target uplink signal according to the transmission power of the reference uplink signal; and the terminal device transmitting the target uplink signal by using the determined transmission power.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for wireless communication, comprising: determining, by a terminal device, a reference uplink signal of a Phase Tracking Reference Signal (PTRS); determining, by the terminal device, a transmission power of the PTRS according to a transmission power of the reference uplink signal; and transmitting, by the terminal device, the PTRS by using the determined transmission power, wherein the reference uplink signal is a PUSCH or a DMRS transmitted on a Demodulation Reference Signal (DMRS) port associated with the PTRS.
2. The method of claim 1 , wherein the PTRS and the reference uplink signal satisfy a specific relationship on at least one of: a frequency domain transmission resource, a time domain transmission resource, a transmission port, or a transmission beam.
3. The method of claim 2 , wherein the PTRS and the reference uplink signal are transmitted through a same port.
4. The method of claim 2 , wherein the PTRS and the reference uplink signal are transmitted through a same beam.
5. The method of claim 2 , wherein the PTRS and the reference uplink signal are transmitted on adjacent carriers.
6. The method of claim 1 , wherein determining, by the terminal device, the transmission power of the PTRS according to the transmission power of the reference uplink signal, comprises: determining, by the terminal device, the transmission power of the reference uplink signal as the transmission power of the PTRS.
7. A terminal device, comprising a processor and a transceiver; wherein the processor is used for determining a reference uplink signal of a Phase Tracking Reference Signal (PTRS), and determining a transmission power of the PTRS according to a transmission power of the reference uplink signal; and the transceiver is used for transmitting the PTRS by using the transmission power determined by the processor, wherein the reference uplink signal is a PUSCH or a DMRS transmitted on a Demodulation Reference Signal (DMRS) port associated with the PTRS.
8. The terminal device of claim 7 , wherein the PTRS and the reference uplink signal satisfy a specific relationship on at least one of: a frequency domain transmission resource, a time domain transmission resource, a transmission port, or a transmission beam.
9. The terminal device of claim 8 , wherein the PTRS and the reference uplink signal are transmitted through a same port.
10. The terminal device of claim 8 , wherein the PTRS and the reference uplink signal are transmitted through a same beam.
11. The terminal device of claim 8 , wherein the PTRS and the reference uplink signal are transmitted on adjacent carriers.
12. The terminal device of claim 7 , wherein the processor is further used for determining the transmission power of the reference signal uplink signal as the transmission power of the PTRS.
